Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a command input support system which is applied to an operating system of a control computer and facilitates command input.

[0002]

2. Description of the Related Art FIG. 18 is a block diagram showing the structure of a conventional command input support system. In the figure, 1 is a command input means for converting an input to an input means such as a keyboard into a code, 2 is a command input error determination means for determining whether or not a code string input from the command input means 1 is a correct command, and 3 is various types. An error message table storing error messages and 4 are display means for displaying error messages on a CRT or the like.

Next, the operation will be described. Consider the case where a keyboard is used as the input means. The key input string input to the keyboard is converted into the corresponding code string by the command input means 1. The code string is input to the command input error determination means 2. The command input error determination means 2 determines whether or not the code string corresponds to a normal command. If the code string is normal, the code string is passed to the command interpreting unit (not shown) of the operating system. The command interpreting unit activates a process corresponding to the input command.

When the input code string is not a normal command, that is, when there is a command input error, the command input error judging means 2 responds to the command input error from among the error messages in the error message table 3. The selected error message is selected and output to the display means 4. The display means 4 controls to display the error message on a CRT or the like.

The above command input support system is described in, for example, MS-DOS (trademark of Microsoft Corporation) 3.3B User's Guide (issued by NEC Corporation in 1989), pages 117 and 169 to 178. There is something like this.

[0006]

Since the conventional command input support system is configured as described above, if the user mistakenly inputs the command part or the parameter attached to the command part, the command or the parameter will be incorrect. That is, although the user is notified by an error message, if the user does not know the correct command or parameter, the user must confirm the correct command or parameter according to the notification according to the notification. In other words, if the user is familiar with the commands and parameters of the system, there is no problem, but if not, it will take time to re-read or reconsider the manual, and to operate the computer during program development. There was a problem that the efficiency was significantly reduced.

As prior arts of the present invention, there are those described in JP-A-63-49817 and JP-A-4-266114.

The present invention has been made to solve the above-mentioned problems, and even if the user is not familiar with the commands of the system, he / she can easily re-enter the correct command when he / she makes a mistake in the command input. The purpose is to obtain a command input support system that can provide a possible environment.

[0009]

A command input support system according to the invention described in claim 1 has an error in a command name registration table in which each legitimate command name is registered and a command portion in a character string input by a user. If there is, the command name that extracts the matching command name from the command name registration table by comparing the preset number of characters of the command part with the characters of each command name in the command name registration table. The search means and the display means for displaying the command name extracted by the command name search means by emphasizing a portion different from the character in the character string input by the user are displayed.

A command input support system according to a second aspect of the present invention is the system according to the first aspect of the invention, in which the user successively inputs a command portion in the character string into the command name search means by mistake.

【Example】

Example 1. FIG. 1 is a block diagram showing the configuration of a command input support system according to the first embodiment of the present invention. In the figure, 5 is a command name search means for searching a command (similar command) that the user may have intended when the user inputs an incorrect command, and 6 is a command name search means for selecting a similar command. The matching character number setting buffer in which the effective number of characters of the comparison code string (comparison character string) is set, and 7 is a command name registration table in which all command names used in the operating system to which this command input support system is applied are set. is there.
Others are the same as those shown in FIG. 18 with the same reference numerals. The command input means 1, the command input error determination means 2, the command name search means 5, and the display means 4 are realized by software.

Next, the operation will be described with reference to the flow charts of FIGS. The command input error determination means 2 reads the character string input as a command on the keyboard via the command input means 1 (step ST
1). Then, it is determined whether the input character string is a correct command (step ST2). If it is correct, the command input error processing ends.

If there is an error, an error message corresponding to the error is selected from the error message table 3 and output to the display means 4 (step ST
3). The display means 4 displays an error message on a CRT or the like. In this way, for example, any of the error messages shown in FIG. 3 is visually displayed. Next, the command input error determination means 2 determines whether or not the command portion of the erroneous input character string is correct (step ST4). If it is correct, that is, if an error has occurred in the parameter portion, the command input error processing ends.

If an error occurs in the command portion, the command name searching means 5 is activated (step ST
5). At this time, the CRT or the like has the EM shown in FIG.
Message 1 is displayed. The command name search means 5 operates as shown in the flowchart of FIG.

The command name searching means 5 first sets the contents of the matching character number setting buffer 6 in the variable A (step ST51). A desired number of valid characters is set in the matching character number setting buffer 6 when the system is started. Further, the command name search means 5 sets the number of characters of the command portion of the input character string in the variable J (step ST52). Further, the number of registrations in the command name registration table 7 is set in the variable K (step ST53). Further, the variable L that can take the values of 1 to K is initialized to 1 (step ST54), and the variable M that can take the values of 1 to J- (A-1) is initialized to 1 (step ST55).

Then, the command name search means 5 compares the Lth command name in the command name registration table 7 with the Mth character to the {M + (A-1)} th character of the input command (step ST56). Input command Mth
If there is a match in the character string of the Lth command name from the first character to the {M + (A-1)} th character, the command name, that is, the Lth command name in the command name registration table 7 is set. , And "which command name do you want to input?" Together with the character string are output to the display means 4 (steps ST57, ST58).

The display means 4 highlights a portion of the command name different from the character string in the input command input by the user by blinking or changing the color.

In the Lth character string in the command name registration table 7, from the Mth character of the input command to the {M + (A
-1)} If there is no match up to the first character, M +
Until the value of (A-1) reaches J, the value of M is increased by 1 and the processes of steps ST56 to ST57 are performed (step ST
59, ST60). From the Mth character to the {M + (A-
1)} up to the third character, or when the value of M + (A-1) reaches J in step ST59, the above processing is performed for all commands in the command name registration table 7. It is confirmed whether the name has been executed (step ST61). If it has been executed, the command name search / display processing is terminated. If not, the value of L is incremented by 1 and the processing from step ST55 to ST61 is performed for the next command name in the command name registration table 7. (Step ST62).

Next, a specific example will be described with reference to FIG. As shown in FIG. 5, it is assumed that "CONT" is input as an incorrect input command. It is also assumed that "2" has been set in the matching character number setting buffer 6.
It is assumed that n command names are registered in the command name registration table 7. Therefore, A = 2, J = 4, K = n
Is. By the processing of steps ST54 to ST62,
[CO], “ON”, and “NT” in “CONT” are compared with the character strings of each command name in the command name registration table 7, so that “COPY”, [COUNT],
[DATEON] and “PRINT” are step ST5.
Extracted in 8.

Then, as shown in FIG. 6, the extracted command names are displayed on the screen as command candidates. Here, "PY" for "COPY" and "UN" for "COUNT"
T] and the like are highlighted.
